However, eventually the authorities started to block other DNS options, too. Late on March 22, hundreds of online users claimed that "the VPN method" remained the only way to enter Twitter. The Hürriyet Daily News has verified that most DNS options, if not all, are currently blocked.

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. DNS-tweaking can be used not only to circumvent blocking of websites, but also for faster browsing. A virtual private network (VPN), on the other hand, enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network.

The Turkish authorities have not released any statement regarding the crackdown on DNS hosting services, which is believed to be based on another executive order, not a court ruling.

However, they have released a memo to explain the government's position. The statement reads that there are "hundreds of court rulings in Turkey" ordering Twitter to remove content, but the San Francisco-based social media company has yet to abide by them.
